Abstract

Carboxylic acid anhydrides of the formula RCO-O-COR', e.g., acetic anhydride, are facilely prepared by reacting, in an essentially anhydrous, liquid phase containing an aprotic organic solvent, (i) a compound of the formula RX, (ii) a carboxylate of the formula (R'COO-)nAn+, and (iii) carbon monoxide, said reaction being carried out in the presence of a catalytically effective amount of a salt of cobalt tetracarbonyl halide, at a temperature ranging from about 0 DEG to 200 DEG C. and under a pressure which is less than or equal to about 600 bars.
